To all lwhom t may concern: v

Be it known that I, HARVEY L. HOPKINS, a citizen of the United States,and a resident of Chicago, in the county .o-f Cook and State ofIllinois, have invented certain new and useful Improvements inMowing-Machines, of which the .following is a full, clear, and exactspecification.

My invention is concerned with mowing machines, more especially of therule-joint or vertical-lift type, in which the finger bar is pivoted tothe main frame, or some connected portion thereof, at the shoe, so'thatthe finger bar can be raised to a vertical position, or substantiallyso, for transporting the machine; and it is designed to improve saidmachines by transferring apart of the weight of the cutting apparatusfrom the ground to the main axle when the team is pulling the machine,thus lightening the draft by lessening the effective weight of thecutting apparatus on the ground as it is dragged thereover, andimproving the traction by throwing a part of the-weight of thecuttingapparatus o-n the driving wheels. My invention furthercontemplates utilizing the draft connections to the cutting apparatusas` a medium whereby any desired portion of the weight of the pole .maybe carried by the draft. It also contemplates an arrangement of thedraft connections whereby the whiifletrees may rise Figure l is a.sectional -view in side clef vation; and

Fig. 2 is a v detail of a portion of the machine as seen 'from the rearof the gag lever and the finger bar. n

The draft wheels 10 are journaled upon the axle 11, upon which ismounted the frame 12 in any customary manner, and the tongue 13 may alsobe connected with said bar 16 is pivoted tothe yoke 17, which in turn ispivoted on theend 18 of the coupling frame (provided the coupling-frametypo of machine is employed) in the customary manner, and thetiltinglever 19 may be connected by a. link 20 with the arm 21 of saidyoke to vary the angle at which the shoe 15 is presented to the groundover which it travels. The lifting lever 22 is pivoted at 23 upon themain frame or a casting carried by the tongue, and is connected by alink 24C with the inner end of the gag lever 25, which is pivoted at 26to the horizontal bearing 27 of the yoke 17, so that the outer end ofthegag lever 25, coperating with a lug 28 extending upwardly andinwardly from the shoe l5, serves to swing the outer end of the fingerbar 16 upward when the lifting leveri'22 is pulled back in the customarymanner. All the construction heretofore described may beV of theordinary type, and I have here illustrated the ordinary McCormickconstruction.

Pivotally mounted upon the bolt 29, or some other suitable projectionextending from the side of the tongue 13, is a clevis yoke member 30,which has a yoke 31 for the whifle't'rees, and an elongatedvertical slot32, through which the bolt 29 passes, so that the said clevis yoke 30 isfree to rise and fall in order to keep itself in alinement with thedraft connections and the points on the breasts of the horses where thedraft comes. An arm 33 extending rearwardly and to one side of the4clevisyoke 30 coperates. with the under side of the tongue 13 ftolimitI the rearward position to which the yoke, a pulley mounted on thegag lever, a In Witness whereof, I have hereunto set helically-coiledcontractile spring connected my hand and affixed my seal, this 21st dayat one end to the elevis yoke, and a chain 0f February, A.
